Splicing is fun

I overlooked it for a long time, until one day I realized that I hadn't untied most knots on my boat(s) for years. Got a fid and a guidebook and started experimenting, and soon my Lightning had 3 mm Dyneema and eye splices everywhere
I've tested "no-bury" splices like those once or twice, and they seem to be strong enough. If that rope is Marlow Excel Control, you can even take the core out as it's the cover that takes the load. (And you probably noticed that the black fibres don't melt.)
Southeast Sailboats generally know what they're doing, but there's no guarantee that their (or anybody else's) equipment is fully legal, nor are they even responsible for that. (The sailor always is.)
The relevant class rules are about making a distinction between "optional" blocks and "builder supplied" fittings, and you can attach hooks and the like only to the former. It makes no sense whatsoever, but that's how it is

Enforcing is still whole another matter.
One can be highly skeptical about anything that comes out of Russia, but that traveller line looks like perfectly normal Dyneema. Is there a loop at the other end? If not, you have it backwards - the line is intended to be tied to the loop at the apex of the triangle that the traveller forms.
The "even-thickness" rule is not very well-written either, because splice length isn't restricted. I'm pretty sure though that splices aren't intended to extend into cleats!
I used to have marks at the back end of the boom for the outhaul, but once you know where the floating block is located at different settings then you look at that. The same goes for the other systems. In fact, for the vang you look at the boom height off the deck and/or the boom/mast angle, and when adjusting the cunningham you simply look at the sail shape. No need for marks really.
